I don't have a credit card and I don't spend money, but why did I receive the consumption information?

How is that possible? If it hadn't cost money, there wouldn't have been this transaction.

You can go to the credit card website of CCB, click "Billing Points Inquiry", enter your card number and telephone banking password, and inquire about the transaction details of your billed and unbilled transactions.

If you have this transaction, think about where it will be used. If you really can't remember, you can call the customer service hotline of CCB, and the bank will check it for you.
